BOOK-SUPPO RT.

SPECIFICATION forming part of Letters Patent No. 495,585, dated April18, 1893.

Application filed May 23,1892- To an whom it may concern.-

Be it known thatI, ROBERT LEE HECHLER, a citizen of the United States,residing at Richmond, in the county of IIenrico and State of Virginia,have invented certain new and useful Improvements in Book-Supports; andI do declare the following to be a full, clear, and exact descriptionof. the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to certain improvements in book supports, and ithas for its objects to provide an improved device forholding one leaf ofthe book cover and the superimposed leaves thereof when the book isopened, in a level position while entries are being made as more fullyhereinafter explained. These objects are attained by the meansillustrated in the accompanying drawings, in which- Figure 1 representsan open ledger with my device applied thereto; Fig. 2 a front elevationshowing the means of adjusting the device and Fig. 3 a vertical crosssection showing the frame in an elevated position in dotted lines.

Referring to the drawings the letterA indicates a clamp or frameconstructed in two parts indicated by the letters a a which areadjustably held together bya binding screw H which clasps the juxtaposedvertical portions M, M of said frame.

The letter 0 indicates a clamping screw passing through an internallyscrew threaded aperture in the lower part of the clamp or frame,preferably at a point midway between its ends. The said screw isprovided with a swiveled disk, at the upper end which bears against thelower side of the cover of the book and prevents abrasion thereof as thescrew is turned. The lower end of the screw is provided with a milleddisk or button E, by

upon a table or other support and opened at the proper place so as tobring the left hand cover thereof and its superimposed leaves into anapproximately horizontal position as shown in Fig. 1. The parts of theframe A are then adjusted by means of the screw H, so that the part awill rest upon the top surface of the cover at its left hand edge andthe roller G upon the top of the table. The clamping screw E is thenturned up, so as to bind the device to the cover and thus hold the samein the desired position.

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, is-

In a book support the combination of the frame A constructed in twoparts a a, the latter being provided with a roller G adapted to restupon the surface of adesk or table, of the binding screw I-I passingthrough a slot in the vertical portion of the part a into athread edaperture in the vertical portion a, and the vertical clamping screw 0passing through the horizontal portion of the part a and provided with aswiveled disk at its upper end and adapted to clamp a book cover to thehorizontal portion of the part a substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
